Left: photometry of Jekyll (blue) and Hyde (green) from the UV to the sub-millimeter. The observed photometry is shown with diamonds(downward pointing triangles indicate 2σ upper limits for measurements of significance less than 2σ). The bestfitting dust model is shown with an pale line,and the total model (dust and stars) is shown with a darker line. For illustration, for Hyde we also show a dust model assuming T_dust = 40 K, which overpredicts the MIPS, Herschel and SCUBA fluxes. The dust model for Jekyll is only illustrative, and was simply normalized to match the constraint from the 744 μm flux. Right: zoom-in on the stellar emission, shown in S_λ instead of S_ν. As described in the text, the 5.8 and 8 μm photometry are shown here only for Hyde; the fluxes in these bands were obtained from aperture photometry of the whole system, with the predicted contribution of Jekyll subtracted. Here we also show in light blue the range of possible SEDs for Jekyll when all the IRAC photometry is ignored in the fit.
